Integrated control device, system and method for magnetic bearing and motor based system

Abstract

The present invention relates to the technical field of magnetic bearing and motor control, in particular to an integrated control device, system and method based on a magnetic bearing and motor system. The method includes: acquiring the operating data of the motor and the magnetic bearing in real time; synchronously processing the operation data of the motor and the operation data of the magnetic bearing and generating a control strategy according to the processing result; outputting a control signal according to the control strategy to coordinately control the operation states of the motor and the magnetic bearing. The embodiment of the present invention combines the traditional magnetic bearing controller and the motor controller into one to realize data synchronous processing and unified control. The operating data of the motor and the operating data of the magnetic bearing are shared in real time, reducing the response time of the system and greatly saving The cost is reduced, and the reliability of the system is improved while reducing the number of electronic components.

Description

technical field [0001] The invention relates to the technical field of control of magnetic bearings and motors, in particular to an integrated control device, system and method based on a system of magnetic bearings and motors. Background technique [0002] The energy storage system changes the kinetic energy of the system by increasing and decreasing the speed of the shafting to achieve energy storage. In order to enable the shafting to achieve the fastest speed, the existing technology uses magnetic suspension bearings. However, the system’s The magnetic bearing controller and the motor controller are independent of each other, so that the magnetic bearing system and the energy storage system only have less communication. Since each uses an independent controller, the number of electronic devices in the system is greatly increased, which not only increases the cost, but also The overall reliability of the system is reduced, and at the same time, there is a phenomenon of co...

In order to enable the shafting to achieve the fastest speed, the existing technology uses magnetic suspension bearings. However, the system’s The magnetic bearing controller and the motor controller are independent of each other, so that the magnetic bearing system and the energy storage system only have less communication. Since each uses an independent controller, the number of electronic devices in the system is greatly increased, which not only increases the cost, but also The overall reliability of the system is reduced, and at the same time, there is a phenomenon of communication delay, which makes it impossible to realize real-time information sharing
